PATENT OFFICE Figure8 is a detail of the operating means i for the sash locking means. i

Referring to the particular embodiment o-f the invention here illustrated, 10 indicates the window frame or casing having the usual vided with an insert 13 to permit the lower the upper end of the casing, or lintel, is prog vided with an insert 13 to premit the lower sashes 11 and 12. In the present instance,

sash to be raised above the upper sash enough to allow theupper sash to be lowered belowthe lower sash, when that has been raised, and then swung to washing'position, as illus-' trated in Figure 3.

Theslide grooves for the sashes are in fact slide grooves for two pairs of runners generally designated as 14 and 15, to which the respective sashes are pivoted at the bottom, as at 16 and 17, so that they may be swung vertically inwardly.

The pivot 17 of the lower sash is prefer I ably'ofi'set inwardly to permit the sash to clear the sill piece when being swung to ventilating position with the sash down and the runners locked, as illustrated by Figure 2. Notches or slots are provided at the ends ofthe sill piece to receive the lugs of the offset pivot when the sash is down. The runners may be constructed of a wood base or body 18 (Figures 5, 6 and 7), shaped to fit the slide grooves of the window casing, and ametal strip or facing 19 suitably secured to the wood base and preferably rebent or booked, as at 20 igure 7) to enter a vertical groove 21 on the outer side of each sash and make a weather proof joint when the sash is swung to closed position. The upper end of each runner is longitudinally channeled at the rear to receive the weight tape or cord 22 (Figure 5) of the usual counter-balance weight,the end of which is anchored to a screw 23 at the lower end of the channeled portion. 1 f

The middle andlower portions of the wood base or body of each runner are channeled on the outer face to a point short of its lower end and this channel is covered by a metal I no vertical slot 24 opening into the channel but not extending as far down the runner. In

effect, therefore, each runner is formed with a hollow or tubular portion, into the upper portion of which the slot 24 opens. For a distancesubstantially coextensive with the provided with a spring pressed catch adapted to cooperate with the notches or seats in the ratchetband 25, and this may consist of a plunger, such as a ball 30, seated in a here or hole'in the block and impelled by a compression spring 31. The arrangement is such that movement of the two blocks as a sash is swung down to open position or up to closed position Will cause the balls or plungers 30 to successively engage the seats 26 and tend to yieldably hold the blocks and,

"therefore, the sash, in any desired position.

For cooperation with this sash holding means when desirable, as when heavy sashes are to be used, the lower end of the channel in the runner contains a coil spring 32 (Figure 4), which is preferably of such length as to leave some free space between its-upper endand the lower side of the block 27 when the sash is closed and the block is in its uppermost position, as in Figures4 and 5. This will allow initial opening movement of the sash to'be-made freely, but, as the sash swings downwardly and the weight to'be supported by the operator of the sash increases, the block will contact with. and compress the spring 32 more and more, thus effectively neutralizing a suflicient amount of the weight of thesash to make upward swinging movement comparatively easy. At the same time, the resistance to movement afforded by the ratchet is so gauged as to neutralize the thrust of the spring 32 and permit the sash to remain in any desired open position.

In connection with means for locking the sashes against sliding movement when the window is closed and" also when the sashes have been moved vertically to open the window any desired distance at the top or bottom, the runners 14 are provided with a suitable number of vertically spaced notches in their exterior surfaces. For purposes of illustration, the upper runners 14 are shown as having notches 33 (Figure 2) in their lower ends, while the lower runners 15 are shown with similar notches34 at their upper ends. When the wvindow is closed, these notches are 1n the same horizontal plane. The upper runners may also be .provlded with similar notches 33 and 33 for a purpose to be described. The lower runners may also be provided with additional notches at desired points in their lengths, as at 34*. For cooperation with the several notches the window casing has mounted in it at eachside, in the same horizontal plane as that in which the notches and 34 lie when the window is closed, with a pair ofv spring pressed latch pieces or plungers 35 and 36 (Figure 7) housed in boxes or holders37 and 38 set in the material of the window jamb or casing.

known manner used in connection with ordi-v nary door latches. The outer end of each rod passes through a suitable rosette or bearing socket 41 securedv to the surface of the window casing and formed with an annular flange 42 within which an enlarged cylindrical portion on the hand piece or end. of the shaft may turn. The rod 39 is pressed axially outwardly by a spring 43 surrounding'the rod and held between a collar 44on the rod and an annular flange 45 on the end of a thimble 46 set in the material of the casing and surrounding the rod 37. The socket 41 is formed with opposite notches 47 on its inner side (Figure 8) and the enlarged end of the rod has opposite lugs 48, against which the collar 44 bears and which are adapted to seat in the. notches and be held there by the thrust of spring 43.

With the sash locking mechanism just described, the plungers 35 and 36 will seat in the notches 33 and 34 when the sashes are respectively raised and lowered to close the window, as in Figure 2. As the upper sash is then seated behind a depending guard 49 at its upper edge, it can neither be swung nor moved vertically, while the lower sash is correspondingly locked by the plunger seated in the notch 34 at its upper end. He-

ferring to Figure 8,v a quarter turn given the hand pieces 40 to dotted line position will cause lugs 48 to seat in notches 47 and lock the rods 39 with the plungers 35 and 36 withdrawn from possible engagement with any of their complementary notches in the sashes, andthe sashes are then, free to'slide. A slight push and reverse turn to full line position causes the lugs 48 to leave the notches and ride on the edge of the opening in socket 41, and the sashes are locked. The sashes may, of course, be locked in, partly raised and lowered positions by provision of such notches as 33 in the upper sash and 34* in the lOWer sash. In the present instance the notch 33 is shown as positioned a sufficient distance above notch 33 to permit the upper sash to be lowered and locked in position to clear the guard 49, when it can be swung to ventilating position and into engagement. with stops 50, as shown in dotted lines in Figure 2. This sash is thus locked against sliding and further tilting movement.

To permit similar tilting of the lower sash to ventilating positions, the sides of the window casing may be provided with an arcuate series of seats or notches 51 cooperating with thumb latches 52-on the sash, thus providing for variable. tilting adjustment thereof and securely locking the sash in position. Ordinary thumb latches 53 may be provided on the upper sash to prevent tilting when that sash is partly lowered.

The runners 14 and 15 project only slightly beyond the side panels of the window frame, as best shown in Figure 7, and the lower sash can be tilted on its offset pivot 17 without raising it. Therefore, the sashes can be partly opened by tilting to ventilating positions, as indicated by the broken lines, Figure 2, without admitting rain or objectionable horizontal air currents or drafts as the longitudinal edges of the sashes will lie close to the side panelsof the frame and, as the lower sash tilts on the inwardly offset aXis of pivots 17, there is no opening produced at the lower edge of the lower sash. This feature constitutes an important advanta e of my window construction;

or ready access to the respective sashes from the inside of a room, as for washing or repair, the upper sash can be lowered and swung to the position of Figure 8. At the same time, the lower sash can be brought down from the extreme upper position shown in said figure sufliciently to clear the stops 50 when it can also be swung inwardly in parallel relation to the upper sash.

It will accordingly be evident that a window structure has been providedembodying novel features giving it a wide range of movements and adjustments and permitting the sashes to be readily set in various open posi tions and securely locked, and also one in which the handling of the sashes during swinging movement is made easy by resilient devices for sustaining the weight of the sashes.
